I hope that you edit your comment because writing first is just too silly and sad. As for OP your hopefully ex boyfriend did you a huge favor! Now you no longer have to deal with him, and you can go find someone who doesn't need to be told not to have sex with other people.

Enough with the "plot twist" comments!!! There really is no need for it, Ops' life is not a murder/mystery/whodunit, fiction, paperback novel. Nor a theatrical production of some kind that requires a "plot twist" to be evident in the script so the actors know how to perform.

That plot twist bull shit just started didn't it? Literally just today? Man, for one day it sure is annoying as all hell. Plot twist this, plot twist that.. Plot twist! This shit is fucking dumb, and so are the people who say it.

It's nothing personal, 88. Believe me that's not the case, I speak for only myself when I say it's one of the dumbest new little trends that I really, really hope doesn't take off. I read that phrase like 6 times already today. 5 times too many, in my opinion, but again, nothing against you as a commenter, 88.

Just a possibility here, maybe this was the boyfriend's first serious and committed type of relationship and he didn't understand what that type of relationship details. Of course, it is obvious to most people and would not absolve the boyfriend from being idiotic. Then again there is another possibility. The boyfriend is actually more of a friend with benefits kind of deal, but OP thought there was more to their relationship than there really was. These possibilities are more improbable than the boyfriend just being an idiotic asshatted moose.

Golden_Warrior has a point. If they have only been out a few times, he might think they are just fooling around and not exclusive. It wouldn't be the first time a woman has assumed there is more to the relationship than the guy did.

36 golden_warrior does have a valid point. Is he really her boyfriend or are they just dating? It kind of sounds like the "boyfriend" didn't know they were to be exclusive.
I still feel bad for the OP nonetheless because apparently she didn't know they were at different commitment levels.

All I was trying to say is that we shouldn't jump the gauntlet and crucify him. For some the relationship is exclusive when both parties agree to go on a date. While others, the relationship doesn't become exclusive until a month has been passed. All I'm saying is that we shouldn't judge him until we know the longevity of their relationship.

Well, golden_warrior, you kind of have a point but I don't get this thing about being told to be exclusive. Either OP's "boyfriend" wants to be exclusive or doesn't and it needed to be discussed together. Not one person just ordering the other one to not have sex with others.

Op used the word boyfriend - her guy may not have. Some people go on one date and think they are boyfriend/girlfriend. Some don't think of themselves as exclusive until they talk about it and decide that's where they want to be.

You could argue that if he cared about her, he wouldn't sleep with anyone else no matter what their official status is, and you're right! But maybe he doesn't think of op as his girlfriend, just some chick he's having fun with.

However, the excuse of "you should have told me we were exclusive" is bullshit. He is implying that their relationship status is purely based on op deciding where they are and telling him. He should have made his feelings clear if he wasn't into the relationship.

Perdix, I usually agree with your comments, but that "ignorance is 9/10 of the law" is BS. Any judge will tell you flat out that ignorance is NOT an excuse.
That being said, I know too many people (male and female) in friends with benefits relationships to give this one a YDI or FML. It's clear OP was under the assumption it was a monogamous relationship though, so yeah, she should kick him the nuts then to the curb.

There are a lot of people on here, I've seen, that think that they are in exclusive relationships when they clearly aren't. People have different ideas if relationships, so make it clear at the start, save yourself the trouble, and don't always assume shit.
